Just adding to the “a bit of both” chorus. I visualize and then (if still in more doubt than I’m comfortable with) count cubes and check angles in the supposedly matching bits. In some cases I count/check some parts but not others.
(I think my visualization skills are pretty weak, but I may be comparing myself with other mathematicians rather than the general population, which might well produce skewed results.)
